ATTORNEYS United States Patent PIVOTED REMOVABLE SHELF AND MOUNTINGTHEREFOR Joseph P. Zaidan, Philadelphia, Pa.

Application January 14, 1957, Serial No. 633,946

6 Claims. (Cl. 312-325) The present invention relates to pivotedremovable shelves and mountings therefor, and more particularly to suchdevices which are adapted to effectively increase the usable shelf spacewithin a cabinet.

The primary object of the invention is to providea pivoted shelfutilizing a moving pivot whereby a maximum of shelf cross-sectional areamay be used.

Another object of the invention is to provide a shelf mounting of theclass described above wherein the shelf may be vertically adjusted to aplurality of positions.

A further object of the invention is to provide a pivoted shelf andmounting therefor in which the shelf may be readily removed from itsmounting to facilitate the transferring of the contents thereof toanother position.

, Another object of the invention is to provide a shelf structure andmounting therefor of the class described above which is inexpensive tomanufacture, simple to use, and neat in appearance.

Other objects and advantages will become apparent in the followingspecification when considered in the light of the attached drawings, inwhich:

Figure 1 is a fragmentary perspective view of the invention showninstalled in a cabinet.

Figure 2 is a top plan view of the mechanism illustrated in Figure 1,shown partly broken away for convenience of illustration.

Figure 3 is a fragmentary enlarged front elevation of the shelfmounting.

Figure 4 is a fragmentary enlarged horizontal crosssection taken alongthe line 44 of Figure 1, looking in the direction of the arrows.

Referring now to the drawings in detail wherein like referencecharacters indicate like parts throughout the several figures, thereference numeral indicates generally a cabinet in which the inventionis mounted.

The cabinet 10 is of conventional construction having opposite sidewalls 11 and 12, a rear wall 13, a bottom wall 14, a top wall (notshown), and a door (not shown). The top wall and door of the cabinet 10have not been illustrated since their relationship to the cabinet 10 isobvious. The cabinet 10 is provided with an arcuate filler strip 15extending vertically across the corner formed by the side wall 11 andrear wall 13, as best seen in Figures 1 and 2.

The filler strip 15 is secured to the side wall 11 and rear wall 13 byany suitable conventional means. A resilient strip 16 is secured to theside wall 11 forwardly of the filler member 15 and parallel to theforward edge thereof. The forward edge of the side wall 12 is rabbetedat 17 from the top to bottom thereof to form a recess therein.

A round shaft 18 extends vertically from the bottom wall 14 of thecabinet 10 to the top wall thereof so as to be partially received withinthe rabbet 17, as best shown in Figure 4. The shaft 18 is provided witha plurality of vertically spaced circumferential notches 19, the purposeof which will be later described.

A mounting member 20 comprising an elongated cylindrical portion 21having a bore 22 extending axially therein is provided with a laterallyoffset upper end portion 23. A second cylindrical member 24, somewhatshorter than the cylindrical member 21, is provided with a bore 25extending parallel to the bore 22, and the second cylindrical member 24is integrally joined to the laterally extending offset portion 23 inspaced relation to the cylindrical member 21. The cylindrical member 21is provided with a latch bar 26 pivotally secured thereto at 27 andhaving a latch blade 28 secured to the upper end thereof and arranged toextend through the cylindrical member 21 to engage the notch 19 in theshaft 18.

A spring 29 biases the bar 26 into latching position. The latch blade 28by engaging the notch 19 in the shaft 18, supports the mounting 20 inadjusted vertical position on the shaft 18 for rotary movementthereabout. When it is desired to vertically adjust the mounting 20, thelatch bar 26 is pressed inwardly on the end thereof opposite the latchblade 28 so that the latch blade 28 is retracted from its notch 19engaging position, thus releasing the mounting 20 for movement toanother adjusted position.

A shelf, generally indicated at 30, is provided with a horizontal sheet31 and an integral upstanding flange 32 formed thereon. The panel 31 isprovided with a plurality of ventilating openings 33 extendingvertically therethrough to permit the ready passage of air through thpanel 31. A rod 34 is arranged in a generally rectangular form and isprovided with a vertically extending offset end portion 35 which isadapted to be received in the bore 25 of the mounting 20. The rod 34 ispositioned in contact with the underside of the panel 31 and is securedthereto by any suitable means,such a's welding or the like.

The shelf 30 has the corner 36 thereof opposite the offset end portion35 of the rod 34 arcuately truncated, for reasons to be assigned. Thecorner 37 of the shelf 30 diagonally opposite to the corner 36 isarcuately truncated as at 38 in a concave curvature, for reasons to beassigned.

In the use and operation of the invention, the shelf 30 is movedforwardly in the cabinet 10, and the mounting 20 swinging on the pivot18 draws the corner 37 toward the shaft 18, while the corner 36 pivotsoutwardly away from the rear wall 13. As the shelf 30 swings clear ofthe cabinet 10, it pivots not only on the shaft 18 center but alsopivots about the offset end portion 35 of the rod 34 in the socket 25 sothat the shelf 30 can swing completely out of the cabinet 10 tofacilitate removal of the material stored thereon. After the shelf 30has been swung out of the cabinet 10 it can be lifted vertically bysliding the offset end portion 35 of the rod 34 axially out of the bore25.

The corner 36 is arcuately truncated, as best shown in Figure 2, topermit the shelf 30 to swing past the wall 11 on which it wouldotherwise drag. The filler member 15 is formed to conform to the shapeof the truncated corner 36 so that when the shelf 30 is in the positionillustrated in Figure 2, no gap exists between the shelf 30 and thecabinet 10. The resilient strip 16 serves to bias the shelf 30 intoengagement With the wall 12 as the shelf 30 is swung into its containedposition within the cabinet 10. The concave arcuate truncation 38 of thecorner 37 permits the shelf 30 to swing past the shaft 18 without binding thereagainst.

As illustrated in dotted lines in Figure 4, the shelf 30, in being swungto contained position within the cabinet 10, engages the side 12 whichassists in carnming the shelf 30 into its fully contained positionwithin the cabinet 10. When the shelf 30 has been moved inwardly of thecabinet 10 to nearly its final position therein,'a door (not shown)closing across the face of the front edges of the side walls 11 and 12will push the shelf 30 into its fully contained position within thecabinet 10.

Having thus described the preferred embodiment of the invention, itshould be understood thatnumerous structural modifications andadaptations. may; be, resorted to without departing from the scope/ofthe appended claims.
